Experiències en PBL en els estudis d’enginyeria del disseny

L’estructura curricular d’aquests estudis potencia competències transversals i específiques per a l’activitat projectual, en la generació de productes industrials, així com les capacitats creatives i innovadores. Per aconseguir aquestes competències, les diferents assignatures de cada curs estan interrelacionades amb les assignatures de projectes, on el grau de complexitat va creixent a mesura que avancen els cursos. Com objectiu principal proposem que l’estudiant arribi al final de l’assignatura amb dos projectes ben definits, on ha d’haver aplicat de manera satisfactòria els coneixements adquirits a les altres assignatures

Prediction of the bulking phenomenon in wastewater treatment plants

The control and prediction of wastewater treatment plants poses an important goal: to avoid breaking the environmental balance by always keeping the system in stable operating conditions. It is known that qualitative information — coming from microscopic examinations and subjective remarks — has a deep influence on the activated sludge process. In particular, on the total amount of effluent suspended solids, one of the measures of overall plant performance. The search for an input–output model of this variable and the prediction of sudden increases (bulking episodes) is thus a central concern to ensure the fulfillment of current discharge limitations. Unfortunately, the strong interrelation between variables, their heterogeneity and the very high amount of missing information makes the use of traditional techniques difficult, or even impossible. Through the combined use of several methods — rough set theory and artificial neural networks, mainly — reasonable prediction models are found, which also serve to show the different importance of variables and provide insight into the process dynamics

Application of a support system to the design of wastewater treatment plants

This paper presents a case study that explores the advantages that can be derived from the use of a design support system during the design of wastewater treatment plants (WWTP). With this objective in mind a simplified but plausible WWTP design case study has been generated with KBDS, a computer-based support system that maintains a historical record of the design process. The study shows how, by employing such a historical record, it is possible to: (1) rank different design proposals responding to a design problem; (2) study the influence of changing the weight of the arguments used in the selection of the most adequate proposal; (3) take advantage of keywords to assist the designer in the search of specific items within the historical records; (4) evaluate automatically the compliance of alternative design proposals with respect to the design objectives; (5) verify the validity of previous decisions after the modification of the current constraints or specifications; (6) re-use the design records when upgrading an existing WWTP or when designing similar facilities; (7) generate documentation of the decision making process; and (8) associate a variety of documents as annotations to any component in the design history. The paper also shows one possible future role of design support systems as they outgrow their current reactive role as repositories of historical information and start to proactively support the generation of new knowledge during the design process

DAI-DEPUR: an integrated and distributed architecture for wastewater treatment plants supervision

The activated sludge process - the main biological technology usually applied to wastewater treatment plants (WWTP) - directly depends on live beings (microorganisms), and therefore on unforeseen changes produced by them. It could be possible to get a good plant operation if the supervisory control system is able to react to the changes and deviations in the system and can take the necessary actions to restore the system’s performance. These decisions are often based both on physical, chemical, microbiological principles (suitable to be modelled by conventional control algorithms) and on some knowledge (suitable to be modelled by knowledge-based systems). But one of the key problems in knowledge-based control systems design is the development of an architecture able to manage efficiently the different elements of the process (integrated architecture), to learn from previous cases (spec@c experimental knowledge) and to acquire the domain knowledge (general expert knowledge). These problems increase when the process belongs to an ill-structured domain and is composed of several complex operational units. Therefore, an integrated and distributed AI architecture seems to be a good choice. This paper proposes an integrated and distributed supervisory multi-level architecture for the supervision of WWTP, that overcomes some of the main troubles of classical control techniques and those of knowledge-based systems applied to real world systems

Generalized Higher-Order Voronoi Diagrams on Polyhedral Surfaces

We present an algorithm for computing exact shortest paths, and consequently distances, from a generalized source (point, segment, polygonal chain or polygonal region) on a possibly non-convex polyhedral surface in which polygonal chain or polygon obstacles are allowed. We also present algorithms for computing discrete Voronoi diagrams of a set of generalized sites (points, segments, polygonal chains or polygons) on a polyhedral surface with obstacles. To obtain the discrete Voronoi diagrams our algorithms, exploiting hardware graphics capabilities, compute shortest path distances defined by the sites

Innovación docente interdisciplinar. El uso de la expresión gráfica computacional en la transdisciplinaridad de la arquitectura, la ingeniería y el arte en el E.E.E.S.

En el proyecto de innovación docente cada uno de los participantes aportó su visión conceptual de los problemas y sus resoluciones en equipos formados por estudiantes de disciplinas humanísticas y técnicas, con perspectivas diferentes de la realidad, y por lo tanto, también del planteamiento de la estrategia para la resolución y del desarrollo y la eficacia de la solución. En definitiva, se les ha preparado para la adquisición de los conocimientos, habilidades, destrezas y actitudes básicas necesarias para desenvolverse sin problemas en el actual modelo laboral europeo, siendo el Espacio Europeo de Educación Superior el escenario en el cual se ha desarrollado el proyecto de innovación

Adaptació del portafoli de l'alumne a l'assignatura de dibuix als graus d'enginyeria

L’article presenta l’ús de l’eina del portafoli de l’alumne a l’assignatura d’expressió gràfica als nous graus d’enginyeria. Volem presentar els canvis que s’han realitzat a l’àrea de coneixement per adaptar-se a les assignatures basades en el pla de Bolonya. L’ús del portafoli docent de l’alumne s’ha revelat com un mètode valuós per a l’avaluació continuada, no tant així per a l’obtenció de la nota final. Presentem l’estratègia d’aplicació, el cronograma i els resultats obtinguts. Tanmateix fem una crítica dels detalls a millorar i els canvis que realitzarem cara als propers cursos. L’objectiu que cerquem els professors de l’àrea és adaptar l’assignatura al pla de Bolonya, assegurant que el treball continuat de l’alumne i el procés d’autoaprenentatge són correctament valorats. Tanmateix cal assegurar que l’estudiant realitzi una tasca d’aprenentatge autònom fora d’aula, que el temps dedicat a la resolució d’exercicis s’adeqüi a la quantitat de crèdits ECTS assignats, i que creixi el paper del professor com a tutor que revisa l’adquisició de competències. Aquesta experiència tendeix a que els estudiants centrin la seva activitat en el portafoli docent

New delay-dependent stability criteria for uncertain neutral systems with mixed time-varying delays and nonlinear perturbations

The problem of stability analysis for a class of neutral systems with mixed time-varying neutral, discrete and distributed delays and nonlinear parameter perturbations is addressed. By introducing a novel Lyapunov-Krasovskii functional and combining the descriptor model transformation, the Leibniz-Newton formula, some free-weighting matrices, and a suitable change of variables, new sufficient conditions are established for the stability of the considered system, which are neutral-delay-dependent, discrete-delay-range dependent, and distributeddelay-dependent. The conditions are presented in terms of linear matrix inequalities (LMIs) and can be efficiently solved using convex programming techniques. Two numerical examples are given to illustrate the efficiency of the proposed method
